Values are calculated as mean ± SD (n = 3)
and A. fumigatus, respectively. It was observed that the fungus utilized rice bran
meal better than mustard meal. They accumulate 45–47% lipid in their biomass. The
highest biomass production was measured to be 15.01 g/L, 6.94 g/L, and 13.24 g/L
in A. niger, A. heteromorphus, and A. fumigatus respectively. Another study reported
the production of 9.2% lipid from 13.6 g/L of biomass in A. fumigatus and 17.9%
lipid from 14 g/L biomass in A. niger (Ali and El-Ghonemy 2014) similar to our
study.
